Tannoy Mercury mSUB10
Documentation on the Tannoy Mercury mSUB10 is thin. Here is what the record shows. It is an active subwoofer from Tannoy's Mercury line, with a built-in amplifier rated at 75 watts RMS continuous and 150 watts peak. Period listings use two name variants, "Mercury mSUB 10" and "Mercury mSUB10". The spelling with a space before the number is more common in European sources.
One period source gives the driver as 25 cm. Owner comments are sparse. They describe soft, deep, well-controlled bass that works in both home cinema and stereo setups. One forum user said their unit "works well and pumps clean tight bass," with a cosmetic caveat about the grille cover. A second-hand listing in South Africa said the unit was "new in box including manual and wiring diagrams."
No production years, original price, dimensions, weight or frequency response figures have surfaced in the surviving record. The Hi-Fi Database page that lists the model shows a modest 7 votes and no written reviews. Used prices seen in Poland in 2026 hover around PLN 740-990.
What is known, in brief:
- Active subwoofer with built-in amplifier
- 75W RMS continuous / 150W peak
- Driver referenced as 25 cm
- Name appears as both "mSUB 10" and "mSUB10" in period listings
